Beste Munition Glock 17. It will work well, and as edf702 mentioned, it's a good idea to break the pistol in with this high energy ammunition. Here’s something that’s not widely known:

Maximum (upper limit) pressures for 9 x 19mm ammunition to be used in glock pistols should not exceed 43,500 pounds per square inch/3000 bar. Firearms must be shipped via fedex overnight to your selected ffl. I recenly put a new sub 2k, 9mm, g17 on layaway and desire to select it up by the stop of the month.
